Fuel Polishing Service Considerations

Fuel Polishing Service Considerations

Fuel polishing is the process of filtering diesel fuel from storage tanks to eliminate contaminants. This process is also known as diesel cleaning services or diesel polishing. The fuel polishing filtration process removes microbial particles, water, off-road and on-road sludge from oil wells.

Fuel polishing is preferred because it requires no downtime. The fuel system remains operational during the filtration process, resulting in a clean tank and new clean fuel. Fuel tank maintenance costs are relatively low compared to the high price of diesel fuel. Fuel polishing restores the quality of diesel fuel to meet U.S. Standard Test (STM) D975-10 standards.

Why polish diesel fuel?
Markets Requiring Fuel Polishing Services
Benefits of Fuel Polishing
Removes impurities from the fuel and restores it to ASTM.D975-10 standards for on-road and off-road acceptable diesel fuel.
Polishing costs less than a complete fuel replacement.
It extends fuel tank life by removing sludge from the fuel tank and keeping it there.
Polishing keeps the fuel system online and eliminates the need to shut down the tank during use.
Underground and Aboveground Fuel Tank Filtration Process
This is a proven and successful fuel filtration process that results in fully polished and usable fuel that meets ASTM.D975-10 standards.

Make sure you have proven in-house filtration equipment to push fuel through multiple filters.
Extract multiple fuels from the lye solution for later comparison with filtered fuel samples.
Before beginning the filtration process, pump out any standing water from the bottom.
The process should start at a high filtration level to remove heavy and large particles.
The circulating fuel is gradually returned to the tank through smaller sized filters, depending on the size and amount of particulate impurities.

The recycling process also removes any moisture from the bottom of the tank.
An antimicrobial agent is inserted to inhibit the growth of harmful algae and microorganisms.
What are the stages of fuel filtration?
Removal of large particles
Fuel filtration using a 25 micron filter
Water separation and fuel filtration using a 5 micron filter
Injection of antimicrobial additives
Testing of polished samples and comparison with pre-polished fuel composites
Why remove diesel sludge?
The removal of diesel sludge is critical to the overall maintenance of your fuel and fuel tank. Debris and impurities in the sludge can clog over time. When crowded debris combines with other fuel contaminants, it can cause sludge to build up, fall out of the fuel, and land at the bottom of the tank.

Fuel Contamination Problems
Fuel contamination has many problems.

It can worsen the condition of the inner fuel tank.
It can damage the generator’s diesel engine, which provides automatic power in the event of a power outage.
When the contamination is severe, it can cause the electrical system to completely shut down.
Types of fuel contamination
1. Particulate contamination
Particulate pollutants can be rust, solid particles, soot and dirt. Once formed, particles can damage or clog the engine.

2. Microbial contaminants
They consist of yeast, organisms, molds and bacteria. They can cause corrosion and clogging of fuel system filters.

3. Water contamination
Water contamination in fuel includes separated, dissolved and emulsified water. They can lead to liner corrosion and erosion.

Why do I need to polish my diesel fuel?
When the quality of diesel fuel is disturbed by toxins such as chemicals, bacteria and mold particles.

It can clog diesel engines and affect their performance.
When it clogs fuel feeders and systems, it can affect fuel flow in cold weather.
It will not function effectively in diesel equipment and vehicles.
Markets in Need of Fuel Polishing Services
Fuel polishing is the best solution for maintaining backup power systems such as generators in the commercial sector. Many facilities prefer fuel polishing services because they do not require downtime. Fuel polishing remains ASTM compliant and the system remains online during the filtration process.

Critical facilities such as research, medical, transportation, and data storage rely on full polishing services when inspecting, installing, cleaning, and maintaining the diesel fuel and fuel tanks that power their backup systems.

If someone is concerned about the integrity of their fuel, believing it does not meet ASTM specifications or could cause problems, then fuel polishing is the ideal solution to restore it to like-new condition.
